Iatented Dec. 12, ll9llti.

To all whom it may concern Be it known that I, PHILIP N. BRAUN,

of Syracuse, in the county of Onondaga, in

the State of New York, have invented new and useful Improvements inCollar-Ironing Machines, of which the following, taken in connectionwith the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in collar-ironingmachines of the class set forth in the patent to W. J. Quinn No.792,454: issued June 13, 1905, except that it refers .more particularlyto the circular collar-supporting plate upon which the folded collarsare placed by hand preparatory to subjecting the fold to pressure in asuitableshaping head for smoothing the folded edge of the collar. Thesecollars are usually folded on a line parallel with but at one side ofthe lengthwise seam uniting the front to the back so that the fold isalways at the side of the seam adjoining the front portion of the collarto avoid any appearance of the seam and it, therefore, follows that thefold must include the hemmed ends of the exposed front portion of thecollar where they meet at the front of the neck, thereby producing anextra thickness the width of the hem at the ends of the fold.

In the use of the rigid collar-supporting plates heretofore employed,particularly in ironing the edges of collars in which the hems at thefront ends of the fold were of considerable thickness there was alwaysmore or less liability of subjecting the folded portions of the hem toexcess pressure while other portions adjacent such folded hem would beleft more or less rough by reason of the inequality of pressure at thethick and thinner portions of the folded edge.

My object, therefore, is to overcome this objectionable result by makingportions" of the edge of the collar supporting plate upon which thecollar is placed and particularly those portions where the hems at theends of the collars rest Suiiiciently resilient to yield under pressurerelatively to other por tions of such edge during the pressing operationso that the exposed edge of the collar will have a continuous, smoothappearance. In other words, I have sought to provide the collarreceiving edge of the plate with transversely yielding portions locatedat such relative positions and of such lengths that the hems at the endsof the collars of difl'erent sizes will be, brought into contacttherewith, when placed on the plate, so that when the collar issubjected to pressure, in a suitable shaping head, the thickenedportions of such hems will cause a slight depression of the adjacentyielding edges of the plate and thereby allow the top edge of the collarto contact with the shaping head under nearly uniform pressure at allpoints, leaving such edge in a uniformly smooth condition, withoutliability of breaking or overstraining the threads of the fabric at thefolded portions of the hems.

Other objects and uses will be brought out in the following description:

In the drawings-Figures 1 and 2 are perspective views of slightlymodified forms of my improved collar supporting plate. Fig. 3 is anenlarged face view of the upper portion or collar receiving edge of theplate shown in Fig. 1. Fig. 4: is a face view of a further modified formof my invention, in which the ends of the spring arms extend to thecollar supporting edge of the plate and are disconnected one from theother, so as to allow free and independent action of either one of them.Fig. 5 is an elevation, partly in section, of a collar ironing machineembodying my improved collar supporting plate.

In order that my invention may be clearly understood, I have shown aplatform -7 on which is arranged a standard 8-- which serves to supporta shaping device or ironing head 9-. This shaping device comprises ajacket -'1() having an inlet 1l-- and an outlet 12- for a heating fluid,such as steam, adapted to heat the ironing portion of the head which isformed with a groove -13- for the reception,

as hereinafter described, of the collar support having a collar thereon,to mold the collar under pressure.

Suitable guide brackets 14 are secured to the platform 7 and slidablymounted therein is a stem or shaft 15- having an arm 16 at its lower endwhichfis connected by a strap 17 with oted an arm .-24- thereon.

a crank 18 on an operating shaft 19-. A lever 20 is formed at one end ofthe shaft so as to permit the same to be readily rotated. A cross strip21 is secured to the upper end of the shaft '15 and has standards --22at the ends thereof, to the upper end of which is piv- -23 having anupright Each of the uprights '2l is adapted to support a collarsupporting plate l secured thereto in any suitable manner. These platesare adapted to be moved successively and by hand into head with which it1s and out of registration with the shaping device 9 and be projectedinto the shaping device when in registration therewith by verticalmovement of the shaft 15.

In Figs. 1 and 3, I have shown a circular collar supporting plate .1 ofthin spring metal, such as spring steel, divided through one side at 2for permitting radial expansion and contraction to conform more readilyto the size and form of the shaping adapted to coact during the pressingoperation, and also to compensate for any inequalities of thickness indifferent portions of the collar during such operation. The main featureof the invention, however, consists in providing the collar supportingedge of the plate with yieldmay be united or covered by mg portions 3 ator near the meeting ends or division -2 and of suffieientcircumferential length to form yielding rests for thethieker portions ofthe folded hems at the ends of the collar, so that when the collar issubjected to pressure against a suit able shaping die, the portions ofthe collar supporting edge of the plate adjacent the thickened portionsof the collar will yield and allow the exposed edge of the collar to bepressed with a uniform degree of smooth ness at all points in itslength. These results are accomplished effectively by providing theportions 3 of the plates with a series of diagonally disposed slots 4forming intervening diagonally disposed spring arms -5, the free ends ofwhich a yielding rim or coping member 6, forming a continuous smoothsurface for supporting the collar, as shown in Figs. 1 and 2, or may befree and disconnected, as shown in Fig. 4. When the rims 6+ areemployed, they are sufliciently resilient to allow any one or more ofthe free ends of the arms 5 to b sprung downwardly and laterally,independently of the other arms, according to the position of thethickened portion of the collar, said arms being sufliciently stiff andresilient to return the rim to its normal position when the pressurethereon is relieved.

In Fig. 3, I have shown a collar 11 in section as resting upon the rimor coping 1ne1nher (3 and as provided with a thickened portion, such asa hem a, at one end to illustrate the effect of pressure upon the collarat the thickened portion thereof, which causes a slight depression ofthe rim 6 at 6, thereby similarly depressing the free ends of theadjacent arms 5 against their own tension and allowing the upper surfaceof the folded edge of the collar to be smoothed in a straight linethroughout its length, by contact with a suitable shaping head, notshown.

The slots 4 and spring arms 5 of the collar supporting plate, shown inFig. 2, are very similar to those shown in Figs. 1 and 3 except that thearms are slightly wider, while the ends of the slots are offsetlaterally, thereby reducing the width of the arms at these points andincreasing their resiliency or ability to yield under comparativelylight pressure.

As previously stated, the free ends of the arms -5, shown in Fig. 4, aredisconnected, but disposed in close juxtaposition, and are slightlyundercut in one edge near their ends to establish a substantiallycontinuous working edge or rest for the folded edges of the collars andat the same time allow the free end of any one of the arms to yieldtransversely of the plate, independently of the other arms, in case anextra thickness of collar should be registered with that particularpoint of the plate.

It is obvious that many other modifications might be made foraccomplishing the same results without departing from the spirit of thisinvention, the essence of which resides in a collar supporting ringhaving depressible edge portions arranged to underlie the folds in thehems near the ends of the collar, in combination with an ironing head,the ring and the head adapted to have relative movement for interfittingthe ring with the collar thereon and the socket, to mold the collarunder pressure.

What I claim is:

1. In a collar ironing machine, a circular collar supporting platehaving portions thereof near one edge slotted diagonally to formresilient arms.

2. In a collar ironing machine, a circular collar supporting platehaving diagonally disposed spring arms.

3. In a collar-ironing machine, a circular collar support having aseries of yielding members arranged side by side about its axis, andmeans integral with said members for holding them in concentric relationto said axis.

4:. In a collar-ironing machine, a circular collar support having aportion thereof composed of' series of vertically yieldalole fingers,and an integral coping member covering the upper ends of said fingers.

5. In a collar ironing machine, a substantially circular collar supporthaving a portion thereof composed of a series of diagonally disposedfingers.

6. In a collar ironing machine, a substan tially circular collar supporthaving a portion thereof composed of a series of diagonally disposedyielding fingers, and a cop1ng 1 PHILIP NATHANIEL BRAUN.
